Roll for rotary cutter and rotary cutter

A rotary cutter comprising a cutter roll and an anvil roll, the cutter roll comprising:

• a barrel portion having a circumferential surface and a pair of end surfaces located respectively at opposite ends of the circumferential surface;
• a cutting blade located on the circumferential surface, the cutting blade having a cutting shape;
• and
• a pair of guide rings located respectively at opposite ends of the circumferential surface in a longitudinal direction,
• the anvil roll comprising:
• a barrel portion having a circumferential surface that receives the cutting blade and a pair of end surfaces located respectively at opposite ends of the circumferential surface, only one of the cutter roll and the anvil roll comprising:
• a pair of shafts connected to the barrel portion and having an axis that coincides with an axis of the circumferential surface,
• at least one of the cutter roll and the anvil roll comprising:
• a pair of first depressions located respectively at the pair of end surfaces of the barrel portion and having a ring shape or a cylindrical shape, the pair of first depressions each having a depth direction that is parallel to an axis of the barrel portion, or a pair of first depressions located respectively at the pair of end surfaces of the barrel portion and each having a ring shape
• extending around the shaft, the pair of first depressions each having a depth direction that is parallel to the axis of the shaft;
• a pair of first bearings located respectively in the pair of first depressions and each being in contact with the shaft of the first depressions, the pair of first bearings not contacting an outer wall that forms the circumferential surface;
• and
• a pair of first bearing boxes located on an outside of the pair of first depressions and having support portions to be in contact with a support frame or a pressure mechanism, the pair of first bearing boxes supporting the respective first bearings.
